Induction of Hair Follicle Regeneration in Rat Ear by Dermal Papilla Cell Microcapsules

    TLDR Microencapsulated cells can regenerate hair follicles in rat ears.
    The study aimed to induce hair follicle regeneration in rat ears using microencapsulated dermal papilla cells (DPs). The DPs were encapsulated with alginate-polylysine-alginate and transplanted into rat ears. Histological examination revealed that fully developed hair follicles were present at the implantation site, differing from normal rat ear follicles in configuration, number, size, and differentiation degree. The study concluded that microencapsulated DPs retained their physiological function to induce follicle regeneration.

      A study that outlines the full model for androgenic alopecia (AGA) which links DHT to cellular senescence in dermal papilla cells, and suggests black chokeberry as a source of cyanidin 3-O-arabinoside polyphenol with potential anti-oxidant properties that could reverse this process. The post encourages reaching out to experts in anti-aging and longevity to research treatments involving the polyphenol.

      community Verteporfin and Microneedling

      in Treatments 5 months ago
      Clinical studies by Dr. Barghouthi and Dr. Bloxham indicate that Verteporfin, when used with FUE and FUT hair transplantation methods, shows promise in hair follicle regeneration and minimal scarring due to its ability to inhibit Yes-associated protein (YAP). Microneedling at depths of 3-3.5mm, combined with Verteporfin, could potentially reactivate dormant follicles, although the optimal dosage and application method are still under investigation. Concerns remain about the DHT sensitivity of regenerated follicles, highlighting the need for further research to optimize trauma levels and Verteporfin concentrations to achieve effective and scar-free hair regeneration.

      in Technology  10 upvotes 2 years ago
      HairClone aims to rejuvenate miniaturizing hair follicles through follicle banking and cell expansion, with treatments potentially available in the UK by 2022. The process involves extracting, storing, and cloning hair follicles, but full regenerative treatments will take many years to develop.

      community Does melatonin dissolve in isopropyl alcohol

      in Technology  6 upvotes 1 year ago
      The conversation discusses making a topical melatonin solution for hair loss treatment, questioning if isopropyl alcohol can dissolve melatonin. Melatonin is soluble in lipids and alcohol, but it's unstable and should be mixed fresh regularly; it may help hair growth by affecting certain cellular signaling pathways and has anti-androgenic effects.
